Mies van der Rohe Is Watching You

The top radical is 'rain' (雨), meaning 'storm'.
Right radical is a
Non-General Use character that originally meant 'clam/cutting tool',
which acts
phonetically to express 'shake/tremble'. This character originally
indicated a violent storm that caused things to shake and tremble.
Henshall
suggests as a
mnemonic: 'Rain makes clam shake and
tremble.'
